[JBoss Portal] - Best practice for resource URLs
by free1000
I want to use images in the portlet I am creating, but can't find any examples of how best to form the URLs for this.
I initially thought that URLs should just be relative to the web-app that wraps the portlet, but these don't appear to work as I have coded them.
The web-app has the a folder called images and content image.jsp
warfile structure
portlet.war
| images
| image.jsp
| jsp
| view.jsp
| META-INF
| WEB-INF
| classes
| ImagePortlet.class
| portlet.xml
| portlet-instances.xml
| portlet-object.xml
| web.xml
In view.jsp I want to insert an image tag which displays images/image.jsp
<image src="images/image.jpg" /> does not display. I expect that I need to do more work on the URL to achieve this. Can someone provide me with a sample, or point me to the docs where this is described because I can't locate this information.

[JBoss Seam] - Re: begin method invoked from a long running conversation, t
by MSchmidke
Hallo bfo81 [mein Englisch scheint wirklich furchtbar zu sein :-)],
no, there is absolutely no second @Begin in the whole application.
Trying nested isn't what I want. So I tried join, but this only leads to a lot of other error messages:
| org.hibernate.exception.GenericJDBCException: Cannot open connection
| Caused by: org.jboss.util.NestedSQLException: Transaction is not active: tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=WPIT0174/15, BranchQual=, localId=15]; - nested throwable: (javax.resource.ResourceException: Transaction is not active: tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=WPIT0174/15, BranchQual=, localId=15])
| javax.ejb.EJBTransactionRolledbackException: javax.ejb.EJBNoSuchObjectException: Could not find Stateful bean: ak5u-xp76gl-epuxyl69-1-epuxzz2s-8
|
All those errors occur since I've coded the absolutely very first inputText JSF element in my life. I'm building my first page for a few days now. Until now I only had outputText and so on. Just to see something.
Next step is turning the outputText into inputText - and - crash.
By the way, the page is rendered anyway. Looks fine, even with all those error messages in STDERR. But the next request gives an Tomcat error report.
